TECHNICAL FIELD

The present invention relates to a 7-membered ring compound having achymase inhibitory activity and useful as a pharmaceutical for theprevention and/or treatment of diseases, in which chymase is involved,such as bronchial asthma, urticaria, atopic dermatitis, allergicconjunctivitis, rhinitis, rheumatoid arthritis, mastocytosis,scleroderma, heart failure, cardiac hypertrophy, congestive heartfailure, hypertension, atherosclerosis, myocardial ischemia, myocardialinfarction, restenosis after PTCA, restenosis after bypass graftsurgery, ischemic peripheral circulatory disorders, hyperaldosteronism,diabetic retinopathy, diabetic nephropathy, nephritis,glomerulosclerosis, renal insufficiency, psoriasis, solid tumor,postoperative adhesion, glaucoma, and ocular hypertension, and themethod of production thereof and starting compounds useful for the same.

BACKGROUND ART

Chymase is stored as an ingredient in granules of mast cells (MC), whichare one of the inflammatory cells closely related to inflammation, andis widely present mainly in the tissue such as skin, heart, vascularwalls, intestines etc. (see Non-Patent Document 1). Human chymase isknown as an enzyme for specifically producing angiotensin II (i.e., AngII) from angiotensin I (i.e., Ang I) independently from angiotensinconverting enzyme. There is a report that, in human cardiac tissue, 80%of the production of angiotensin II is derived from by chymase (seeNon-Patent Document 2). Ang II is known to be closely related toregulation of the blood pressure, diuretic regulation, and hypertrophyand remodeling of the cardiovascular system, that is, the migration andproliferation of smooth muscle cells etc. and the growth of theextracellular matrix in the cardiovascular system tissue. From thesefindings, it is suggested that chymase is closely related tocardiovascular lesions through production of Ang II. In addition toproduction of Ang II, it is reported that chymase has the followingactions based on its protease activity: 1) degradation of theextracellular matrix (see Non-Patent Document 3), activation ofcollagenase (see Non-Patent Document 4), and production of collagen (seeNon-Patent Document 5); 2) processing and activation of inflammatorycytokine, for example, release of latent TGF β1 from extracellularmatrix (see Non-Patent Document 6), activation of latent TGFβ1 to activeTGFβ1 (see Non-Patent Document 7), and activation of IL-1β (seeNon-Patent Document 8); 3) activation of stem cell factor (SCF) whichinduces differentiation and proliferation of MCs (see Non-PatentDocument 9); 4) degradation of apolipoprotein B in LDL (see Non-PatentDocument 10) and degradation of apolipoprotein A in HDL (see Non-PatentDocument 11); and 5) conversion of big endothelin to a bioactive peptidecomprised of 31 amino acid residues (ET(1-31)) (see Non-Patent Document12). Further, it is reported that chymase stimulates rat peritoneal mastcells to induce degranulation (see Non-Patent Document 13) and thatadministration of human chymase intraperitoneally to mice orsubcutaneously to guinea pigs induces infiltration of eosinophil andother leukocytes (see Non-Patent Document 14), and causes continuousincrease of vascular permeability not through the action of histamine(see Non-Patent Document 15). These various reports relating to theaction of chymase suggest that chymase plays an important role in theprocesses of tissue inflammation, repair, and healing, and in allergicconditions. It is believed that in these processes, the excessivereaction of chymase is involved in various diseases.

From the above-mentioned findings, a chymase inhibitor can be expectedto be useful as a pharmaceutical for the prevention or treatment of forexample, bronchial asthma, urticaria, atopic dermatitis, allergicconjunctivitis, rhinitis, rheumatoid arthritis, mastocytosis,scleroderma, heart failure, cardiac hypertrophy, congestive heartfailure, hypertension, atherosclerosis, myocardial ischemia, myocardialinfarction, restenosis after PTCA, restenosis after bypass graftsurgery, ischemic peripheral circulatory disorders, hyperaldosteronism,diabetic retinopathy, diabetic nephropathy, nephritis,glomerulosclerosis, renal insufficiency, psoriasis, solid tumor,postoperative adhesion, glaucoma, and ocular hypertension, and otherdiseases.

On the other hand, small molecule chymase inhibitors are already shownin books (see Non-Patent Document 16) or review articles (see Non-PatentDocuments 17, 18, and 19). The efficacy of several inhibitors amongthese in animal disease models has been reported (vascular lipiddeposition: see Patent Document 1, heart failure: see Non-PatentDocument 20, myocardial infarction: see Patent Document 2, seeNon-Patent Document 21, see Non-Patent Document 22, aortic aneurysm: seePatent Document 3, restenosis: see Patent Document 4, atopic dermatitis:see Patent Document 5, pruritus: see Patent Document 6, eosinphilia: seePatent Document 7, fibrosis: see Patent Document 8). Further, recently,in addition to the chymase inhibitors described in the above-mentionedbooks and review articles, imidazolidinedione derivatives (see PatentDocument 9), phosphonic acid derivatives (see Patent Document 10),benzothiophensulfonamide derivatives (see Patent Document 11), imidazolederivatives (see Patent Document 12), triazolidine derivatives (seePatent Document 13), pyridone derivatives (see Patent Document 14),thiazolimine and oxazolimine derivatives (see Patent Document 15), andenamide derivatives (see Patent Document 16) are disclosed as novelchymase inhibitors. However, there are no examples of the above chymaseinhibitors being practically used as pharmaceuticals.

Further, 1,4-diazepan-2,5-dione skeleton compounds similar in structureto the present invention are disclosed in documents (see Non-PatentDocuments 23 and 24) etc., but none has the electron withdrawing groupsuch as a carbonyl group, sulfonyl group, or other electron withdrawinggroup at the 4-position nitrogen atom like in the present invention.Further, there is no disclosure at all of chymase inhibitory activitylike in the present invention. Further, Patent Document 17 andNon-Patent Document 25 disclose a 1,4-benzodiazepine derivative as a7-membered lactam derivative having a carbonyl group, sulfonyl group, orother electron withdrawing group at the 4-position nitrogen atom, butthese derivatives differ in skeleton from the present invention.Further, there is no disclosure at all of chymase inhibitory activitylike in the present invention.

Further, as examples of production of a non-fused 1,4-diazepan-2,5-dionederivative similar to the present invention, a 7-membered ring closurereaction using lactamization etc. are reported in Non-Patent Documents26 and 27. However, up to now, there has been no report of a productionmethod characterized by introducing an electron withdrawing group at the4-position nitrogen atom of a 1,4-diazepan-2,5-dione derivative, like inthe present invention. Further, there has been no report up to now of aproduction method of 1,4-diazepan-2,5-dione derivative characterized byan intramolecular alkylation reaction at the portions corresponding tothe 4-position nitrogen atom and 3-position carbon atom, like in thepresent invention.

Test Example 1 Measurement of Inhibitory Activity of Test Compound forHuman Chymase

The inhibitory activity of the compounds of the present invention forrecombinant human chymase was measured by the method of Pasztor et al.(Pasztor et al., Acta. Biol. Hung. 42: 285-95, 1991). That is,recombinant human chymase was diluted to an appropriate concentration bya 50 mM tris-hydrochloride buffer (pH 7.5), 1M sodium chloride, and0.01% (v/v) Triton X-100 to obtain an enzyme solution. A 10 mM dimethylsulfoxide (hereinafter referred to as DMSO) solution ofSuc-Ala-Ala-Pro-Phe-MCA (Peptide Institute) was diluted 20-fold at thetime of use by 50 mM tris-hydrochloride buffer (pH 7.5), 1M sodiumchloride, and 0.01% (v/v) Triton X-100 to obtain the substrate solution.75 μl of the enzyme solution was mixed with 5 μl of the test compound ina DMSO solution, and then incubated for 10 minutes. 20 μl of thesubstrate solution was added to the mixture, and incubated for a further10 minutes at room temperature. The reaction was stopped by adding 50 μlof 30% (v/v) acetic acid. The intensity of the fluorescence (Ex380 nm,Em460 nm) of the fluorescent substance MCA produced by the degradationof the substrate was measured by a fluorescent photometer (FluoroscanII, Labsystems Japan). Simultaneously, 5 μl of DMSO was added to areaction instead of the test compound, and was used as a blank. Theinhibitory activity for chymase was calculated based on the value of theblank. Further, the rate of inhibition and the 50% inhibitionconcentration (IC₅₀ value) were calculated. The IC₅₀ values ofrepresentative compounds are shown in Table XII.

Test Example 2 Effect of Test Compounds on Dermatitis Model Induced byRepeated Application of Hapten

Dinitrofluorobenzene (hereinafter referred to as “DNFB”) was used ashapten, and dermatitis was induced in accordance with the method ofNagai et al. (Nagai et al., J. Pharmacol. Exp. Ther. 288: 43-50, 1999).That is, dermatitis was induced by repeated application of 12.5 μl of0.15% (v/v) DNFB (Nacalai Tesque) dissolved in a mixture (ratio 1:3) ofacetone (Wako Pure Chemicals) and olive oil (Wako Pure Chemicals) toboth sides of the right ear, total 25 μl, once a week in 8 week oldfemale C₃H/HeN mice (Crea Japan). As a control group, acetone:olive oil(1:3) was applied by the same protocol. Ear thickness was measured atevery week before DNFB application and 24, 48 and 72 hours after DNFBapplication by using microgauge (Mitutoyo), and ear edema was evaluatedby the increase in ear thickness compared to the ear thickness beforethe first DNFB application. Six compounds of chymase inhibitor (compound91, compound 178A, compound 150, compound 179B, compound 29, andcompound 90) were used as test compounds. The test compound wassuspended in 0.5% hydroxypropylcellulose in distilled water (hereinafterreferred to as “0.5% HPC-distilled water”) and was administered orallyat doses of 2 and 10 mg/kg once a day, every day from just before thefirst application of hapten to the end of the experiment. Further, as acontrol, 0.5% HPC-distilled water instead of the test compound wasadministered by the same methods. The number of mice used in thisexperiment was seven per group.

Transient skin reaction was induced by DNFB application, and thistransient skin reaction was increased gradually with increasing thenumber of DNFB application. As a result of oral administration of testcompound to this model, each test compound remarkably inhibited thetransient skin reaction. For example, when compound 91, compound 178A,compound 150, compound 179B, compound 29, and compound 90 at a dose of10 mg/kg were administered orally, the inhibition rates of the skinreaction at 24 hours after DNFB application at fifth application were26.1%, 20.0%, 29.9%, 32.8%, 31.0%, and 25.1%, respectively.
